Specification of Letters Patent.

Patented June 2, 1914.

Application lec'l March 16, 1912. Serial No. 684,246.

llVindows, ot which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to nialre and use the same, refer.

ence being had to the accompanying drawings, forming part of this specification.

My invention relates to improvements in the construction oi' windows and has reference more particularly to windows having sliding sashes.

The chief objects of the invention are to provide a window in which the sliding sashes may be readily swung inwardly so as to give easy access to the outer side of the saine for the purpose or" cleaning, painting or repairing the sashes, and to provide means whereby convenient access is given to the interior of the back-lining or housing in which the weights are hung.

llVith these and other objects in view my invention consists in the peculiar and novel arrangements and combinations of the several diiiierent parts ot the structure, all as hereinafter fully set forth and then point-cd out in the claim.

l have illustrated a type of my invention in the accompanying drawings, wherein,

Figure l is an inside view of lny improved window shown in elevation with the upper and lower sashes closed. Fig. 2 is a vertical sectional view of the window as shown in Fig. 1. Fig. 3 is a vertical sectional view ot the window with the lower sash holder unlocked and swung inwardly into horizontal position and with the lower sash resting therein. Fie". 4 is a similar view to that of Fig. 3 with the upper sash lowered and swung inwardly upon the lower sash. Fig. 5 is a horizontal sectional view of the parts shown in Fig. 4, the plane ot the section being indicated by line 55, Fig. 4t. Fig. G is a horizontal sectional view ot the parts shown in Fig. 1, the plane oft the section being indicated by line 6 6, Fig. 1. Fig. 7 is an enlarged view partly in vertical section ot a corner of one et the sashes, and shows the details ot the releasalole fastener for the sash-suspender. Fig. 8, is an enlarged view in vertical section of `the window.

the upper part of the lower sash holder and sash, and shows a modification ot the upper member of the holder.

Referring to the drawings, in which like numbers ot reference designate like parts throughout, 1 is a rectangular shaped window trame having an outer sill 2, and an inner sill 3. The lower sash l slides vertically in the groove 5, Vformed between the inner or stop-bead 6 and the parting-strip 7 and the sash is hung from the sash cords or suspenders 8 and 9, (see Fig. 6) which are releasably secured to the sideV rails ot the sash in a nianner hereinafter described, and pass over the usual pulley l0, mounted in the pulley-stile 11, of the traine and which may be connected with the usual counter weights which operate in the back lining or housing 12, of said trame.

"When in its lowermost position, the lower sash ll, rests completely in a swinging trame, the two opposite sides (iEL and Gb of which and the connecting bottoni part 6, are substantially sections of the stop-bead which is applied to the window frame. The upper ends ot the members 6a and G1 are secured together by a suitable rod 13, so that the sash holder thus provided is a tour sided rectangular structure. The rod 18, may also be used as a curtain rod for The holder is provided at its lower inner end with hinges 141 and 15, secured to the sill 3, and these hinges permit the holder to be tilted inwardly on its lower inner edge as an axis. The hinges llA and 15, are provided with springs 16 and 17, respectively, which constantly act to press the holder outwardly and tend to keep it in its normal vertical position. The meeting edges 18 and 19, between the swinging holder and the iXcd parts ti, of the inner or stop-bead, are inclined downwardly and outwardly to permit the holder to be easily moved out oit and into vertical position as shown more particularly in Fig. 8.

At each side, the holder is provided with a releasable fastener or bolt 20, which is mounted conveniently on the inner or stopbead aud is quite concealed therein. These bolts take into keepers 21, on the sides of the holder and serve to retain the latter in secure upright position in the trame, and so that the lower sash can be raised and lowered in its guide grooves in the usual way. then the swinging parting strips 32 and 33 are moved into closed position and Athe swinging frame is closed against the parting strips, the latter are pressed firmly against the shoulders 44 and 45 respectively on the Xed frame and these strips are thereby held in operative positions and in line with the upper lined parting strips. The springs 1G and 17 on the hinges of the swinging frame also serve to press the swinging frame against the parting strips and when the bolts 2O of the swinging frame are closed the swinging parting strips are securely locked in operative position. When the lower sash is in its lowermost position and the bolts 20 are released, the holder may he swung inwardly on its hinges into the horizontal position with the lower sash therein, as shown in Figs. 4 and 5. ln order to facilitateV the swinging of the lower sash into its inward position, I form the outer edges of the side rails of the lower sash 4, with a rabbet or rectangular groove 22 and 23, respectively. This permits a relative lateral movement between the sash and the attached suspenders, so that the latter are moved comparatively little out of their normal vertical positions when the lower sash is tilted inwardlyv on its lower edge, as shown in Figs. 3 and 4. It will also be noted that the Y sash Suspenders 8 and 9, are attached to the side rails of the lower sash near the bottom .thereof and this also serves to render the operations of the sash and its holder much easier. This arrangementrequires a shorter sash cord than where the cord is attached to a higher point'on the side rail of the sash. See Fig. 7.

Access is gained to the interior of the housing for the sash weights, through an opening 24, formed in the pulley stile ll, and provided with a removable cover 25, as shown more particularly in Fig. 3. The cover 25 is held in place by a small screw 26, and when the sash holder is swung into open position, the cover 25 may be removed and full access given to the interior of the hous- 'ing for the weights. The point of location of this opening 24 in the pulley-stile is a convenient one.

The upper sash 27 slides vertically in the groove 2S which is formed between the parting-strip 7 and the hanging stile or outside bead 29 at the outer edge of the window frame. Substantially the lower half of the parting strip 7 is made separate from the other part and this separate part is provided with hinges 30 and 31 which are secured between it and the pulley-stile ll. This permits the lower part of the parting strip to be swung inwardly on its hinges and iatly against the pulley stile, to permit the upper sash, when in its lowermost position, to be moved inwardly and taken out of the frame, as shown in Fig. 4. The hinged section of the parting-strip is indicated by the numeral 32 upon one side of the frame and numeral 33 upon the other, as shown more particularly in Figs. 5 and 6. After the lower sash holder is swung inwardly, as shown in Fig. 3, the hinged sections 32 and 33 respectively of the parting strip are swung inwardly as shown in Figs. 4 and 5, and this gives a clear passage for the removal of the upper sash 27 so that it can be readily drawn out into horizontal position and placed upon the then upper side of the lower sash, as shown in Fig. 4.

The upper sash is provided with sash cords 34 and 35 which pass over pulleys 36 fixed in the pulley stile, and are provided with the usual weights which are located within the housing l2 of the frame (see Fig. 6). The front edges of the side rails of the upper sash 2T are rabheted at 37 and 38 respectively, substantially in the same manner hereinbefore described in reference to the. lower sash and for the same purpose. These sash cords or Suspenders 34 and 35 are attached to the side rails of the sash in the rabbets at points near the lower end of the sash and this serves to shorten the length of the sash cord and also to keep the same out of the way when the sash is drawn out into horizontal position, as shown in Fig. 4. The sash cords are attached to the side rails of each of the sashes in the same way and by means of a detachable fastener comprising a plate 39 which is set in the bottom of the rabbet flush withV the surface lthereof and held in place by means of small screws 40, a recess 4l being formed in the side rail and into which leads an opening 42 in said plate. Before the plate is mounted in position by the screws, the sash cord is threaded through the opening'42 and then tied in a knot 43 upon the inside of the plate, which is then secured in place, as shown more particularly in Fig. 7.

In Fig. 8 I show the upper horizontal member 13a of the sash holder as being constructed of a strip of wood which might be preferred in some constructions instead of the metal rod 13 which is shown in the other figures, but the latter has the advantage of being used as a curtain rod as above stated.

A sash fastener 44 is shown in Fig. l by means of which the two sashes may he locked together when they are both closed. ln the operation of the apparatus the lower sash is moved into its lowermost position so as to be completely within the holder and then the bolts 20 are opened, so that the holder together with the sash may he swung inwardly into a substantially horizontal po` sition, thereby giving complete access to the outside of the glass and sash. Then the swinging sections 32 and 33 of the parting strip are turned inwardly and the upper sash being brought down to the lowest limit of its movement, may be lifted inwardly and access may be thus readily gained to the outside oi the saine by placing it horimentally upon the lower sash and its holder.

By the use of this invention, the outside ot both the upper and lower sashes may be readily cleaned by :i person standing in the room wherein the window is located and without making it necessary for such person to reach outside or" the window or to rest upon the outer sill of the window in order to clean the outside of the window penes, as is the cese in the use of ordinary sliding window seshes.

l wish to be understood as not limiting my invention to the particular construction herein set forth, as modilieetions may be mede in the several diiiiercnt parts thereof, without however departing from the spirit of my invention.

Having thus described my invention, what Uopes of this patent may be obtained for l claim and desire te secure by Letters Petent is In e window et the class described, the combination of upper end lower sliding` seshes, e, window traine having e fixed upper section comprising,` outside end inside beads and a partingetrip, e lower swinging section comprising two side members each having an inside bend, seid window :freine having a, swinging parting-strip forming a, continuation of the upper fixed partingstrip and being held in its operative position by the lower swinging section et the frzune when the latter is in closed position substantially as described.

In testimony whereof, I have hereunto set my hand in the presence of the two subscribing witnesses.
